How do I get Bridge to recognize my Nikon 3000, in irder to "get photos" from camera?

I am unable to use Adobe Bridge to "get photos" from my Nikon 3000. In the past I had intermittent difficulties; Bridge's dialogue box would return, "unable to locate device". Turning the camera on and off would eventually resolve this.
I had to upload on my Mac using the built in photo program. However, the photographs were shot in raw and were downloaded as pegs.
How to I "get photos", through bridge and have them maintain the raw mode?
